Normalized staple-to-staple length and mass for Manufacturer ‘A’ N95 respirators. Upper and lower values are normalized by averaging over the averages of the measurements for upper and lower respirator strap measurements, i.e. 29.7 mm length and 1.10 g mass for the upper, and 24.7 mm length and 0.92 g mass for the lower.
